Having built two object mappers in Ruby (MongoMapper and ToyStore), I would like to throw out a crazy thought. What if, on your next project, you ditch the ORM.
No ActiveRecord. No DataMapper. No anything. Just you and a lower level driver, whispering sweet nothings into Ruby classes and modules. Could you? Would you? DARE you?

MVC inventor Trygve Reemskaug and James Coplien have a new vision for software, called DCI -- Data, Context, and Interaction. Although as conceptually elegant as MVC, and with the same potential to improve software, DCI's innovations are not easily implemented in Java or C#. That is not the case with Ruby, however, which puts Rails developers in a unique position to lead the way.

We all know that Rails is great for building traditional web applications that serve dynamic HTML pages. But more and more, people are reaching to other tools, like Node.js, when they build web applications with a lot of logic in the client. People often use the argument that when you remove the view helpers, there isn't much of value left in Rails.

When we build rich client interfaces in JavaScript for our Rails applications today, we have no other choice than duplicating code and logic in both worlds. In this presentation we will show you how to use Google's V8 JavaScript engine in your Rails application to eliminate those duplications, write model code only once and therefore make your code DRY again.
